LNU2G472MSEHBN

The LNU2G472MSEHBN is a screw‑terminal aluminum electrolytic capacitor from Nichicon’s LNU series, designed for high‑voltage industrial power applications. This polarized, radial can capacitor delivers 4.7 mF capacitance at a 400 V DC rating in a compact package optimized for inverter and regenerative power circuitry.

Engineered for elevated operating conditions, the part supports continuous operation to 105°C and is specified for long life under ripple‑current loading, making it suitable for inverter power supplies, high‑frequency regenerative voltages and high‑speed charge/discharge applications.

Key Features

• Electrical Performance — 4.7 mF rated capacitance with a ±20% tolerance (120 Hz, 20°C) and a rated voltage of 400 V DC for energy buffering and smoothing in power electronics.
• High Ripple Capability — Specified ripple current of 15.8 A at 120 Hz and 22.12 A at 10 kHz, supporting heavy AC and high‑frequency ripple conditions.
• Thermal Range & Endurance — Operating temperature −40°C to +105°C with a load life of 5000 hours at 105°C under rated ripple current and DC bias.
• Reliability Metrics — Leakage current specified as not more than 3√(C·V) μA or 5 mA (whichever is smaller) after 5 minutes at 20°C; endurance, shelf life and charge/discharge tests in the LNU series meet defined capacitance, tan δ and leakage criteria.
• Mounting & Package — Screw terminal radial can package for robust panel or chassis mounting; polarized design with M5 bolt nominal fastening options per series drawing.
• Compact, High‑Voltage Design — LNU series offers high‑voltage capability in a smaller footprint compared to earlier LNT designs, enabling denser power assemblies.
• RoHS Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Inverters — Energy buffering and DC link smoothing in inverter power supplies for motor drives and factory automation.
• AC Servomotor Regeneration — Handling high‑frequency regenerative voltages and rapid charge/discharge cycles in servo systems.
• High‑Frequency Power Conversion — Support for switching and PWM systems where high ripple currents and thermal endurance are required.

Unique Advantages

• High Voltage in a Compact Footprint: 400 V rating with series support up to 525 V delivered in a smaller package than previous LNT models, allowing tighter power module layouts.
• Designed for Sustained Ripple Loading: Specified ripple current ratings at both 120 Hz and 10 kHz provide confidence under AC and high‑frequency operating conditions.
• Extended High‑Temperature Life: 5000 hours at 105°C under rated ripple current ensures long service life in thermally demanding installations.
• Robust Mechanical Mounting: Screw terminal radial can with M5 nominal bolt provisions enables secure mounting and reliable electrical connection in industrial environments.
• Predictable Leakage Behavior: Leakage current limits defined by 3√(C·V) μA or 5 mA provide measurable acceptance criteria for quality control and system design.
